ip'g-lioa'tion filed February 1 To all whom it may concern Be it knownthat L Jianes Toininn'r, e citizen of the United States, residing;Woodward, in the county of Jelierson rein State of Alabama, haveinvented new an, useful Improvements in c}l )l)6 V2Li/6S or which thefollowing is sgeeifieetion.

This invention rel utes to imprrweinenrs in globe valves of that generaltype wherein the valve member consists of e ball. and is so organizedrelatively $0 the valve stem that it may be positively operated by saidstem either to uncover or to close the opening which it controls; or, ina particular pe sition of the stem, may 'fnncfiion n cheek valve, andmay opera e automatically in we cordance with pressure conditions.

The principal object of the invention is to provide a construction orthe type above described wherein the spherieni valve meniiher issupported in novel. manner from veive stem, the relation being; suchthat seiri stem cannofi produce any wear on valve member.

An embodiment of the iiwenrion illuetrated in the accompanying whereinFigure 1 is a 'er-aical iongitndinal seetional View of a valve in whichthe features of the invention are incorporated; Fig. 2 is a detailhorizontal sectional view on the line f22 of Fig. L

der 10 of the head 7. The recess 9 of said head accommodates the flange16 and nut when the ball supporting cage is in its uppermost position.In case it should be necessary to renew the ball, ready access may behad thereto by removing the body 11 from the head 13. The removal of thebody 11 from said head does not, however, interfere with the relationbetween said head and the stem 8. Therefore, the renewal of the valve isa very simple matter.

Having fully described my invention, 1 claim v A globe'valve comprisinga casing having a horizontal web provided with an opening therethroughandohaving a cylindrical neck above said Web, a head forming a closurefor said neck and having its lower portion bell-shaped to provide aninternal clearance alining with said neck and having an internalshoulder circumscribing said clear ance, a valve stem threaded throughsaid head, a ball valve member controlling the opening in said web and asupporting cage for said valve-member comprising; a cylindrical bodyarranged within the neck of the casing and havinga reduced lower portionagainst which the ball valve member rests in an elevated position ofsaid cage, a head carrying saidcylindrical body and having a concentricdepending flange of reduced diameter upon which the cylindrical body is'threaded, said body at its upper end abutting the marginal portion ofsaid last named head and the said marginal portion in the uppermostposition of said-head engaging against the internal shoulder of saidfirstvides a swivel joint between saidstem and mid cage, the bodyofthe-cage being of suchlength that the head of said cage is substantiallyspaced from the ball valve in an vlevated position of the cage.

In testimony whereof I have hereunto set my hind in presenceof-two'subscribing wit-- nesses JAMES R. TORBERT.
